Automaticity Correct Answer (pacing function) is the ability of cardiac cells to generate an electrical impulse spontaneously and repetitively. Excitability Correct Answer the ability of non-pacemaker heart cells to respond to an electrical impulse that begins in pacemaker cells and depolarize Conductivity Correct Answer ability to send an electrical stimulus from cell membrane to cell membrane. Contractility Correct Answer the ability of atrial and ventricular muscle cells to shorten t...

Sensory perception 1.)conscious process of selecting, organizing, and interpreting data from senses into meaningful info 2.)Perception is influenced by the intensity, size, change, representation of stimuli, past experiences, knowledge, attitudes. Stimulus 1.)agent or act that stimulates a nerve receptor Impulse conduction process - sensory functioning also do receptors respond to many stimuli or just one? 1.)receptor receives stimuli, translates it to impulse 2.)impulse travels along nerve pa...
